A Light Dynamical Scalar Boson

Abstract

With the discovery of a scalar resonance at ATLAS and CMS, the understanding of the electroweak symmetry breaking origin seems a much closer goal. A strong dynamics at relatively low scales is still a good candidate. In this talk, the complete effective Lagrangian up to d < 6 will be presented, both for the gauge and the flavour sectors. Interesting features in the flavour phenomenology will be discussed.
